Here’s some body scanning news that actually makes me want to raise my arms — and give some high fives. For the first time, art researchers used a TSA-style scanner on a fresco and found something underneath that other techniques had missed.

J. Bianca Jackson, a postdoctoral researcher based in Paris, and her colleagues specializing in art conservation and restoration decided to study an Italian fresco at the Louvre Museum called ”Trois Hommes Armés de Lances.” The group suspected that it hid images underneath because it had come from Giampietro Campana, a 19th century art collector known for reworking some of the works he acquired.
